| Description |
Coal keeps on doing a noteworthy job in the economic development of a country, particularly in metallurgical industries and power generation sectors. Coal is currently beneficiated predominantly in wet condition. The conventional methods for processing of coarse coal like heavy media bath, jigging etc. utilizes water. In the near future, coal resource and water resource is going to have a reverse distribution thus posing several hurdles to wet beneficiation technologies in coal cleaning. Thus, it is exigent to develop efficient dry beneficiation technology for coal. This paper presents a summarized assessment of performance of an Air Pulsated Stratifier with particular reference to Indian Coal. The study was carried out on coal samples having ash in the range of 30-33%. Response parameters considered for this study were ash reduction and yield of clean coal. Results are found to be encouraging as the experimental trials resulted in absolute reduction of Ash percentage in the range of 7-9% in single stage.
